Abstract
This WSNs coupled with the Internet of Things (IoT) is very much needed in facilitating smart environment like smart cities, industrial automation, healthcare monitoring and environmental monitoring. Nevertheless, WSN-IoT systems are extremely susceptible to security risks such as denial-of-service attacks, malicious node behaviors, manipulation of routing, data manipulation, and privacy breaches due to their distributed, heterogeneous, and resource-constrained nature. Conventional centralized security models are usually insufficient to deal with these dynamic and scale cyber threats. The paper describes a detailed overview of blockchain-based and artificial intelligence (AI)-based security solutions to the distributed WSN-IoT scenarios. The paper examines the security dangers at varying layers of a IoT architecture and surveys the recent frameworks that incorporate machine learning, deep learning, and federated learning along with blockchain technology in managing decentralized trust and identify intrusions. Moreover, performance trade-offs on the effectiveness of security, energy use, latency, and scalability are discussed. Lastly, the research indicates the presence of an open challenge and future research topics of creating secure, scalable, and intelligent WSN-IoT infrastructure. The paper also suggests a solution of integrative AI-blockchain security framework that would have a combination of AI-based intrusion detection and decentralized blockchain trust management.
The analysis shows while blockchain, ML and DL technologies play a crucial role in enhancing IoT security, they each have limitations including scalability, computational overhead, data dependency and lack of flexibility against new cyber threats.

The proposed BlockSafeNet framework achieved significant improvements in secure IoT communication, privacy preservation, and AI-driven cyber threat detection within smart city infrastructures, providing a positive impact on the SC ecosystem.
BELS-IoT is proposed, a novel decentralized protection architecture that integrates a cryptocurrency-based blockchain layer with a multi-layer ensemble learning engine that rewards honest behavior and penalizes malicious activities while maintaining privacy through federated learning with blockchain-verified reputation scores.

As the new applications like smart cities, medical systems, industrial automation, and critical infrastructures, along with the Internet of Things (IoT) technologies, have emerged, the need for real-time data processing at the edge has also grown. Although the edge-based IoT architectures minimize the latency and bandwidth consumption, they also present new security problems because of the distributed implementation, limited computational power, and lack of centralized control. The traditional, cloud-based, and black box artificial intelligence (AI) security system simply does not fit such a context without being transparent, responsible, and sustainable. Furthermore, in the real world, if IoT applications are designated to be safe, they cannot be realized by using black-box decision models without trust, compliance with regulations, and reliability through time. The paper proposes an edge-based IoT security framework to improve the cyber resilience and sustainability and ethical decision-making through the interpretable and responsible AI models. The proposed solution will be based on the use of explainable and light algorithms of machine learning at the network edge to monitor malicious actions and provide friendly explanations of the security actions to a human. It supports interpretability, fairness, accountability, and detection accuracy to detect threats and respond appropriately in dynamic environments of IoT, making the system accountable, fair, and sensible. The study with realistic IoT intrusion data sets proves that the proposed approach is competitive at detection and is more transparent and stable regarding various traffic conditions. The results show the importance of developing AI models that are interpretable and responsible for sustainable, credible, and resilient edge-based IoT security systems.

The integration of IoT into smart cities exposes serious cyber security risks, which old centralized designs would fail to combat. In this paper, the model suggests a unified system that would use AI and block chain technology to protect smart city IoT systems. A lightweight hybrid CNN-LSTM model is used to detect anomalies in real-time at the edge nodes and federated learning with differential privacy can be used to train collaboratively without exposing raw data. Permissioned block chain layer provides tamper-proof records and decentralized management of trust. A query fragment caching algorithm is a resource-optimal query strategy to block chain queries. CIC-IDS2017 and BoT-IoT datasets analysis show 98.6% detection, 97.5% F1-score, 134.6 ms latency, and 2,615 transactions-per-second, and 41% less energy usage than un cached block chain access. The framework is more effective than the current methods in all measures.
